The mean summed skinfold at 6 sites in 20 malnourished Jamaican children was 24.5mm on admission to hospital and 49.8mm on discharge. Marasmic children initially had thinner skinfolds than children with oedematous malnutrition, and they had a highly significant reduction in total specific thermal insulation. During their first week in hospital there was a significant positive correlation between nocturnal mean rectal temperature in the malnourished children and their skinfold thickness and specific thermal insulation. Similar correlations for daytime rectal temperature were not statistically significant. We conclude that loss of thermal insulation may be of importance in the genesis of hypothermia in the sleeping malnourished child, whose posture and inactivity favour a negative heat balance. (AU)

The mean auricular temperature of 10 malnourished Jamaican infants was 0.84§C lower on admission to hospital than it was after recovery. Body temperature was influenced by ambient temperature in the malnourished state. During the rapid growth that accompanies recovery the mean auricular temperature was raised. Five malnourished children with hypothermia were given a standard high-calorie feed, and this caused the body temperature to return to normal levels within two hours in every case. These results suggested that reduced temperature in malnourished children may be an adaptation to conserve calories, and that severe hypothermia in malnutrition results from an acute shortage of energy reserves. Frequent feeding of malnourished chhildren is most important in their management. (Summary)

This thesis describes some aspects of the anatomy and physiology of the thyroid gland in Jamaicans. The purpose of the investigation was to discover if any alteration occurred in thyroid gland activity as a result of the prevailing tropical conditions. Thyroid glands were collected from consecutive post-mortem examinations at the University Hospital of the West Indies. It was shown that the thyroid gland in the average Jamaican weighted somewhat less than is usual elsewhere, but that this reduction could be accounted for by a general reduction in body weight. It was also demonstrated that in this highly selected population, there was a low incidence of goitre and that there was a very low incidence of thyroid nodules. Thyroid function was estimated using a variety of tests involving the use of radioactive iodine. Following a pilot study using the technique of thyroid clearance of radioactive iodine, thyroid function was estimated in a local population the people all being in good health and living in their normal state. The isotopic studies were combined with estimations of stable iodine excretions. It was shown that the daily excretions of stable iodine were on the lower border of normal. This observation is of special interest when the low incidence of goitre is remembered. These results indicated that there is reduced thyroid function in Jamaicans. It is thought that this represents part of the process of acclimatization to a hot environment. The results have been useful also in establishing normal values for a variety of tests of thyroid function which are used in the University Hospital in Jamaica (AU)
